Prospective study on suicidal ideation among Japanese undergraduate students: correlation with stressful life events, depression, and depressogenic cognitive patterns

Development of the Japanese Version of the Test of Self-Conscious Affect-3 (TOSCA-3): A Study among Student and Parent Population

OBJECTIVE

The Test of Self-Conscious Affect-3 (TOSCA-3) is a scenario-based measure of self-conscious emotions. We aimed to create an abridged version of the TOSCA-3 that is appropriate for Japanese populations and has a good fit with the data, as well as validate its subscales.

METHODS

The TOSCA-3 was distributed to (a) a university student population (n = 512: Study 1) and (b) a parent population (n = 260: Study 2). In both studies, items with factor loading < 0.33 were deleted one by one to select culturally appropriate scenarios for each of the six domains of self-conscious emotions. In Study 1, self-conscious emotions were correlated with the other correlates.

RESULTS

Most of the final models showed a good fit with the data. In Study 1, the six domains of self-conscious emotions showed correlations with depression and related items, dispositional coping styles, experiences in childhood, ego function, borderline and narcissistic personality traits, and adult attachment styles, almost in the expected fashions.

CONCLUSIONS

The TOSCA-3 is a useful tool to measure self-conscious emotions among Japanese student and parent populations if a few culturally inappropriate scenarios are deleted.

Perceived abusive supervision and graduate students' suicidal ideation: from the perspective of interpersonal psychological theory of suicide

BACKGROUND

In recent years, the issue of suicide caused by the stress of a contradictory relationship between graduate students and academic supervisors has aroused heated discussion in society. Based on the interpersonal psychological theory of suicide, this study aims to examine the influence of the perceived abusive supervision on graduate students' suicidal ideation and the parallel mediating roles of thwarted belongingness and perceived burdensomeness.

METHODS

We conducted a cross-sectional online survey measuring perceived abusive supervision, interpersonal psychological needs and suicidal ideation among 232 Chinese graduate students. A structural equation model was constructed to test the hypothesis.

RESULTS

The results showed that abusive supervision directly exacerbated suicidal ideation (β = 0.160, 95% CI = [0.038, 0.281], p = 0.009) and indirectly influenced suicidal ideation through thwarted belongingness (β = 0.059, 95% CI = [0.008, 0.110], p = 0.019) and perceived burdensomeness (β = 0.102, 95% CI = [0.013, 0.191], p = 0.018). The indirect effect accounted for 50.15% of the overall effect.

CONCLUSIONS

These findings enrich our understanding of the influence of supervisor-student relationship by integrating the literatures on educational and organizational behaviour, and provide practical insights for psychosocial interventions from the perspective of the interpersonal psychological theory of suicide.

Pre- and Post-Pandemic (COVID-19) Mental Health of International Students: Data from a Longitudinal Study

Purpose

International students are highly vulnerable to the risk of mental health worsening before and during the pandemic (COVID-19). This study investigated international students' mental health pre- and post-pandemic (COVID-19).

Methods

It is a longitudinal study, and data were collected online, pre-pandemic (N = 470) and during the pandemic (N = 420). Using a random sampling technique, a self-administered questionnaire was used to measure mental health, including depression and anxiety.

Results

Findings show that international students' mental health was good in pre-pandemic. Meanwhile, international students were found to be more depressed and anxious during the pandemic. Findings also investigated that in the pre-pandemic phase, young students' and mainly females' mental health was worsened.

Conclusion

This study concluded that students' mental problems are alarming, so the university should provide psychological services for the student's mental health. Post-pandemic is leaving long-lasting psychological effects and will require further investigation.

College students' screening early warning factors in identification of suicide risk

This study aimed to explore the main influencing factors of suicide risk among Chinese students and establish an early warning model to provide interventions for high-risk students. We conducted surveys of students in their first and third years from a cohort study at Jining Medical College. Logistic regression models were used to screen the early warning factors, and four machine learning models were used to establish early warning models. There were 8 factors related to suicide risk that were eventually obtained through screening, including age, having a rough father, and CES-D, OHQ, ASLEC-4, BFI-Neuroticism, BFI-Openness, and MMC-AF-C scores. A random forest model with SMOTE was adopted, and it verified that these 8 early warning signs, for suicide risk can effectively predict suicide risk within 2 years with an AUC score of 0.947. Among the factors, we constructed a model that indicated that different personality traits affected suicide risk by different paths. Moreover, the factors obtained by screening can be used to identify college students in the same year with a high risk of suicide, with an AUC score that reached 0.953. Based on this study, we suggested some interventions to prevent students going high suicide risk.

Common mental health problems among adolescents in sub-Saharan Africa: A systematic review and meta-analysis

Background and aim: This review examined the prevalence of mental health problems among adolescents in sub-Saharan Africa.Methods: The review included studies indexed in the MEDLINE, EMBASE, and PsycINFO databases, supplemented by a search on Google Scholar and tracking of references from articles identified. A total of 725 articles were found, of which 28 met the inclusion criteria. Finally, 22 eligible studies were reviewed.Findings: The pooled current prevalence of mental health problems was 23% (95% CI: 18; 28, I2 = 99.41%). Any depression, 19% (95% CI: 9; 30, I2 = 99.64%), and anxiety, 20% (95% CI: 01; 31, I2 = 99.64%), were the most common mental health problems reported. Attention deficit hyperactivity disorder, 5% (95% CI: 3; 7, I2 = 97.60%), and conduct disorders, 15% (95% CI: 8; 22, I2 = 99.58%), were also significant mental health problems among adolescents in the region.Conclusion: About one in five adolescents in sub-Saharan Africa suffer from one or more mental health problems. The findings have important implications for policy and practice as they indicate that mental health problems are a major public health issue among adolescents in sub-Saharan Africa and that there is a need for effective and context-specific interventions that address mental health.

Depression and suicidality among Bangladeshi students: Subject selection reasons and learning environment as potential risk factors

PURPOSE

This study examined the role of subject-selection reasons and learning environment factors in students' depression and suicidality.

DESIGN AND METHODS

This study surveyed 960 students from five different Bangladeshi universities using questions concerning socio-demographics, lifestyles, subject-selection reasons, learning and academic environment, suicidal behaviors, and the Bangla Patient Health Questionnaire.

FINDINGS

Approximately half of the participants were depressed (47.7%), and just over a quarter reported past-year suicidality (28.5%). Risk factors for both depression and suicidal behavior included not studying at their desired institute, selecting subjects based on future career prospects (rather than choosing what they want to study), not having a study-friendly and research-friendly environment, and unsupportive teachers.

PRACTICAL IMPLICATIONS

The findings will help in formulating policies for educational institutions as well as providing benchmark data for further studies.

Early Trauma and Relationships among Recent Stress, Depressive Symptoms, Anxiety Symptoms, and Suicidal Ideation in Korean Women

BACKGROUND

Evidence continues to accumulate that the presence or absence of early trauma (ET) implies unique characteristics in the relationships between suicidal ideation and its risk factors. We examined the relationships among recent stress, depressive symptoms, anxiety symptoms, and suicidal ideation in Korean suicidal women with or without such a history.

METHODS

Using data on suicidal adult females, 217 victims and 134 non-victims of ET, from the Korean Cohort for the Model Predicting a Suicide and Suicide-related Behavior, we performed structural equation modeling to investigate the contribution of recent stress, depressive symptoms, and anxiety symptoms on suicidal ideation within each group according to the presence or absence of a history of ET.

RESULTS

Structural equation modeling with anxiety and depressive symptoms as potential mediators showed a good fit. Recent stress had a direct effect on both depressive symptoms and anxiety symptoms in both groups. Only anxiety symptoms for victims of ET (standardized regression weight, 0.281; P = 0.005) and depressive symptoms for non-victims of ET (standardized regression weight, 0.326; P = 0.003) were full mediators that increased suicidal ideation. Thus, stress contributed to suicidal ideation by increasing the level of anxiety and depressive symptoms for victims and non-victims, respectively.

CONCLUSION

Tailored strategies to reduce suicidal ideation should be implemented according to group type, victims or non-victims of ET. Beyond educating suicidal women in stress-management techniques, it would be effective to decrease anxiety symptoms for those with a history of ET and decrease depressive symptoms for those without such a history.

Suicidal Behavior and Psychological Distress in University Students: A 12-nation Study

This study investigated the prevalence of suicidal behavior and psychological distress in university students across 12 nations. A total of 5,572 university students from 12 countries were surveyed about suicide ideation, suicide attempts, and psychological distress by means of a self-administered questionnaire. Almost 29% of the samples reported having contemplated suicide and 7% reported attempting suicide. Of the total sample, 51.1% scored above the General Health Questionnaire-12 ≥ 3 cut-off points, 41.6% above the GHQ-12 ≥ 4 cut-off points, and 33.8% scored above the GHQ-12 ≥ 5 cut-off points. While odds of suicide ideation were elevated in Austria and the UK, reduced ORs were detected for China, Italy, Saudi Arabia, Tunisia, and Turkey. Similarly, while odds of suicide attempt were high in Jordan, Palestine, Saudi Arabia, and to some extent in Turkey, reduced ORs were observed for Austria, China, Italy, Japan and the United States. Elevated ORs for psychological distress were seen in Japan, Jordan, Palestine, Saudi Arabia, Tunisia, and Turkey but reduced ORs were noted in Austria, China, Iran, Italy, and the United States. Psychological distress was strongly associated with reports of suicide ideation and attempts. Suicide ideation, suicide attempt, and psychological distress are common in university students but their rates vary depending on the sociocultural context. Due attention should be devoted to the mental health needs of young adults enrolled in higher educational institutions and more cross-cultural research is warranted to better understand the etiology of the observed intersocietal variations in suicidal behavior and psychological distress.

Prevalence of suicidal ideation in Chinese college students: a meta-analysis

BACKGROUND

About 1 million people worldwide commit suicide each year, and college students with suicidal ideation are at high risk of suicide. The prevalence of suicidal ideation in college students has been estimated extensively, but quantitative syntheses of overall prevalence are scarce, especially in China. Accurate estimates of prevalence are important for making public policy. In this paper, we aimed to determine the prevalence of suicidal ideation in Chinese college students.

OBJECTIVE AND METHODS

Databases including PubMed, Web of Knowledge, Chinese Web of Knowledge, Wangfang (Chinese database) and Weipu (Chinese database) were systematically reviewed to identify articles published between 2004 to July 2013, in either English or Chinese, reporting prevalence estimates of suicidal ideation among Chinese college students. The strategy also included a secondary search of reference lists of records retrieved from databases. Then the prevalence estimates were summarized using a random effects model. The effects of moderator variables on the prevalence estimates were assessed using a meta-regression model.

RESULTS

A total of 41 studies involving 160339 college students were identified, and the prevalence ranged from 1.24% to 26.00%. The overall pooled prevalence of suicidal ideation among Chinese college students was 10.72% (95%CI: 8.41% to 13.28%). We noted substantial heterogeneity in prevalence estimates. Subgroup analyses showed that prevalence of suicidal ideation in females is higher than in males.

CONCLUSIONS

The prevalence of suicidal ideation in Chinese college students is relatively high, although the suicide rate is lower compared with the entire society, suggesting the need for local surveys to inform the development of health services for college students.

Hopelessness and Suicide Proneness in U.S. and Japanese College Students

Few empirical studies have focused on the associations among suicide proneness, hopelessness, and depression cross-culturally. The current study examined the potential to determine differences in the overall expression of suicide proneness between Japanese ( n = 396) as compared with U.S. ( n = 417) college students. Depressive symptoms were considered as a potential mediator of the relation between hopelessness and suicide proneness in both samples of students. Preliminary analyses focused on estimates of internal consistency reliability and differential item functioning (DIF) on the measures of hopelessness, depressive symptoms, and suicide proneness. Results of the primary analyses revealed that Japanese students reported more suicide proneness, greater hopelessness, and higher levels of depressive symptoms than did U.S. students. As expected, hopelessness and depressive symptoms were significantly associated with suicide proneness in both cultures. Additionally, the hopelessness–suicide proneness link was significantly mediated by depressive symptoms in both samples. Implications are offered for improved identification and treatment of college students at risk of suicidal behaviors both in the United States and in Japan.

Self-determination: a buffer against suicide ideation

Self-determination was examined as a protective factor against the detrimental impact of negative life events on suicide ideation in adolescents. It is postulated that for highly self-determined adolescents, negative life events have a weaker impact on both hopelessness and suicide ideation than for non-self-determined adolescents. In turn, hopelessness is hypothesized to generate less suicide ideation for highly self-determined individuals. Results from multigroup analyses confirm that both the direct and indirect links between negative life events and suicide ideation were significantly weaker among participants high in self-determination. The protective role of self-determination against negative life events is discussed.
